Hi everybody. I need guidance about a lil debate within my party:
If i have an amulet of mighty fists that has a magical property (flaming, merciful, etc) but doesn't has an enhancement bonus (+1,+2), did my attacks counts as magic to bypass DR/magic ???????
Thank you very much in advance.
No.
Overcoming DR: Damage reduction may be overcome by special materials, magic weapons (any weapon with a +1 or higher enhancement bonus, not counting the enhancement from masterwork quality), certain types of weapons (such as slashing or bludgeoning), and weapons imbued with an alignment.
The +x cost for merciful, flaming, etc, is not providing a +x enhancement bonus to the weapon.
bbangerter is correct, you need to have a minimum +1 enchantment in order for the weapon (or in your case, fists) to qualify to bypass DR/magic.
Note, however, that if the amulet of mighty fists adds energy damage (corrosive, flaming, frost, shock), then the added energy damage is affected by energy resistance and not DR. The DR would apply against the base unarmed/natural weapon attack, but the energy damage is considered separately.
